Hi, We just built a large webserver machine (PII-450, 1GB RAM, 30-odd G of Mylex RAID, 3.3-R) that constantly runs a load of from 1 to 3, even though it's not doing anything (still sitting as a staging server). The initial startup is also very slow; after about 40 of the servers start there's about a 15 second pause, then another 40, pause, etc... This box is running about 170 virtual hosts (and a full class C of addresses aliased to fxp0) under Apache 1.3.9, with each vhost running as it's own user and starting 3 servers at startup, so there are a large *number* of processes, but no swapping with about half a gig of RAM left free. I have maxusers at 512, NMBCLUSTERS at 4096, and the following sysctl adjustments: kern.maxproc: 8212 kern.maxfiles: 100000 kern.maxfilesperproc: 16424 kern.maxprocperuid: 8211 kern.ipc.somaxconn: 512 This is all gathered from various "tuning for a big webserver" posts from the various FBSD lists. systat, vmstat, iostat all look normal, and I've not seen any curious entries in the logs. So that's the info, my questions are "why the load", and "is that OK"? Something seems wrong here, but I'm at a loss. Any ideas where to start looking?
